The water level in the sump is above the pump centre by 3.5mts. The suction pipe of 350mm is for a length of 6mts with a 45 degree bend with a gate valve in suction and a butterfly valve and a nrv in the delivery system.
The problem is there is no pump characterstic curve in hand.
We have...
This is recirculation system. Water pumped by the diesel pump goes to the overhead tank from where it flows by gravity to our blast furnace for cooling.
After heat transfer it again comes back to the sump.
This is a new installation and the engine rpm was checked and found to be 1500.The engine performance is good.
The present water flow is some where around 175m3/hr.
The height of the suction pipe from the top level of the water in the sump is 3.5 mts and the sump volume is 350m3. The delivery...
I have a diesel engine driven pump for my blast furnace. The pump has a discharge rate of 800m3/hr at 50Mts head. The pump is connectd to an emergency Overhead tank which is at an height of 40Mts. The problem I face is the water is not discharged with full volume. The suction pipe is 350 Dia and...
Dear Joe Tank,
The outlet dia of the valve is 430mm.
The pivot distance from the centre of the duct is 475mm.
The distance from the centre of the duct to the counter weights is 1125mm.
The distance from the centre of the pivot to the counter weight is 1600mm.
The lever is intersecting the...
We have a blast furnace working with a top pressure of 0.6Kg/cm2. Whenever we find the top pressure increasing more than 0.6 Kg/cm2 the bleeder valves are not opening on its own.
We have two bleeder valves with 0.4mt dia duct two numbers.
The counter weight on each bleeder is 1500 Kgs.
Please...
What is the pressure drop by installing a duplex filter and a strainer in a system of hot water at 55deg C and a discharge of 300m3/hr and a head of 90mts. The size of the pipe is 250mm.
Is there any method apart from RO by which the TDS could be reduced? For example I have got a well containing 7000ppm TDS and 2000ppm Total Hardness. I would like to utilise this well for industrial purpose for this the TDS should be below 2000ppm and the total hardness <1000ppm. Kindly suggest...
How to reduce the total dissolved salts in water for industrial usage? For example the water with 7000ppm TDS and a total hardness of 2000ppm as to be reduced to 2000ppm TDS and the total hardness to 600ppm? How to go about it withot Reverse Osmosis?
